clinical evaluation of the id now™ ct/ng test

Conditions: Chlamydia Trachomatis Infection; Neisseria Gonorrheae Infection; Asymptomatic Condition

Summary: the objective of this study is to determine the performance of the id now™ ct/ng test in male urine, female urine, and self-collected vaginal swabs when tested by intended users (i.e., untrained operators). id now™ ct/ng test results will be compared to results from up to three (3) fda cleared ct/ng nucleic acid amplification tests (naats) for each sample type.

this is a global study and will be conducted at approximately thirty (30) us clinical study sites and up to five (5) study sites ous in europe, uk and africa. the participating sites in the us will be in different geographical areas. up to 30% of ng positive female participants (by composite comparative result (ccr)) may participate from ous sites. id now™ testing will be conducted by untrained operators (i.e., site staff with limited or no training or hands-on experience in conducting laboratory testing). approximately 7,100 participants will be enrolled. consented participants will provide samples for id now™ ct/ng and comparator assay testing. each female participant will provide a 20-50 ml first-catch urine (fcu) sample, one (1) self-collected vaginal swab sample (svs) and three (3) clinician-collected vaginal swabs (cvs). each male participant will provide a 20-50 ml first-catch urine sample. standard of care (soc) samples should be collected first prior to clinical trial specimen collection. soc vaginal swab should be collected before vaginal swabs (self- and clinician-collected) are collected as part of the study. if sites use urine as soc, then soc urine sample can be taken from the untreated sterile urine cup provided to collect first catch urine for this study. samples will be collected, handled, stored, shipped, and tested according to the applicable package insert(s), as appropriate. the site will record the order of sample collection for each participant. id now™ ct/ng testing will be conducted on fresh samples. the sites will ship samples to a central laboratory for testing with up to three (3) fda cleared ct/ng nucleic acid amplification tests (naats) according to the appropriate package insert(s). the central laboratory may be located outside of the clinical site(s) country for ous sites and thus require shipping of samples outside of the clinical sites(s) country as per compliance. each urine sample will be collected in an untreated sterile urine cup provided by sponsor. the site staff will ensure the urine cup is capped and then invert the urine cup five (5) times to mix. once inverted five (5) times, site staff will test 1.5 ml of urine directly from the specimen cup with id now™ ct/ng within two (2) hours of collection. the remaining urine will be aliquoted into applicable transport tubes for each comparator method (3 tubes) and one (1) retained urine sample (5ml). one (1) self-collected vaginal swab will be collected and placed in sample elution buffer by the participant in a private clinical setting. the participant will be provided with instructions on appropriate collection. three (3) additional vaginal swabs will be collected by a clinician for each of the three (3) comparator tests per product inserts. the order in which svs and cvs are collected will be randomized by participant id number. for participants with an odd-numbered participant id, the svs will be collected first, followed by the three (3) cvs. for participants with an even-numbered participant id, the three (3) cvs will be collected first, followed by the svs. for comparator tests, the order of cvs sample collection will be randomized (appendix b). a portion (1.5 ml) of svs in buffer will be tested with the id now™ ct/ng test within 2 hours of sample collection. id now™ ct/ng test results are investigational and will not be used for patient diagnosis or to guide treatment. after id now™ ct/ng testing, leftover vaginal swab eluate and urine samples will be stored at the site according to sponsor instructions and in the case that further testing is needed, shipped to an abbott location/central laboratory at the sponsor's request. no personally identifiable testing for human dna will be performed on any samples obtained from this study. the abbott location or central laboratory may be located outside of the clinical site(s) country for ous sites and thus require shipping of samples outside of the clinical sites(s) country. the sponsor will perform data analysis. the results of the id now™ ct/ng test will be presented separately for ct and ng. id now™ ct/ng test results will be presented by sample type, by sex, and by symptomatic and asymptomatic status. poc link functionality may be established with each id now™ instrument for remote connectivity.
